A new editorial paper published in the journal Aging argues that in multicellular organisms, neighboring cells are in constant competition. The underlying reasons for aging have long remained elusive. However, in 1977, Thomas Kirkwood hypothesized that organisms might gain a fitness advantage by
Researchers propose a novel aging theory—selective destruction theory —which describes aging as a process not tied to damage accumulation, offering a new perspective in gerontology research.argues that in multicellular organisms, neighboring cells are in constant competition.
However, as our understanding of aging increases, it is becoming increasingly difficult to align all the aspects of aging with accumulating damage. For example, mutations that increase damage accumulation can also increase longevity, while rejuvenation revelations such as parabiosis and Yamanaka factors indicate that youthfulness can be regained without high energetic cost and despite high levels of damage.
